I just posted an essay entitled “A Second Look at Sola Fide,” which I originally wrote in late 2006, as I entered RCIA (I joined the Catholic Church at Easter 2007). One of the key factors that led me to reject Protestantism was the shortcomings of the idea that we are justified by faith alone (sola fide). Martin Luther taught that justification was the doctrine by which the church stands or falls. But I discovered that Luther’s teachings on justification contradicted Scripture: we are taught in James 2:24, for example, that “man is justified by works, and not by faith alone” (RSV). It’s a long one — about 5,000 words — but hopefully a worthwhile read on your part. Enjoy!
